Abstract:
4 k inds of phthalic esters w ere extracted by using ho llow fiberm embrane liquidm icroex traction and the ir samp les were ana lyzed by com bin ingw ith gas chrom atography. The ex traction solven tw as to luene, and the stirrer speed w as 600 r /m in orm ore, and the ex traction time was 50m in. The en richm ent factor ca lcu la ted according to ana lys is results rang ed from 19.8~ 221. The linear range for the de term ination o f PAEs w as 10~ 200μ g /L. The lim its o f detec tion were 0.07~ 0.81 μ g /L. The RSD of the determ ination was 6.8% ~ 9.3%. The recove ries w ere in the range of 92% ~ 106.9%. Th is me thod w as app lied to different wa ters. The resu lts show ed that the concentration of DEP in the lake sam plew as 9.2μ g /L, 6.4 μ g /L o f DHEP in the river sam ple and the concentrations o f DEP and DBP w ere 10.2 μg /L and 9.5 μ g /L respective ly in the sam ple from the campus pond wa ter
